摘要
Spherically symmetric space-times provide many examples for interesting black hole solutions, which classically are all singular. Following a general program, spacelike singularities in spherically symmetric quantum geometry, as well as other inhomogeneous models, are shown to be absent. Moreover, one sees how the classical reduction from infinitely many kinematical degrees of freedom to only one physical one, the mass, can arise, where aspects of quantum cosmology such as the problem of initial conditions play a role.
